In this video of the SABO Academy you’ll see the Square Wave test, a protocol of procedures drawn up by our Technical Office to check the behaviour of our products and ensure their proper validation.
In the first stage the shock absorber, built using the components to be validated, is placed in a temperature testing chamber and cooled to -30 °C and left to stabilise for 24 hours so that all its component parts have cooled.
In the second phase it is removed from the chamber and tested on our MTS test bench, using a detection programme with ‘standard’ braking characteristics.
Afterwards there begins a third test phase: this is called the Square Wave phase and involves 10 complete cycles in which the shock absorber undergoes a thrust on its vertical axis at a speed of greater than 4 m/s: the stroke is established as a function of shock absorber size.
Once this test has been completed – and as long as the shock absorber has no oil leaks or other faults – we proceed with another standard test is which it is heated to a temperature of 130° at a speed of 0.52 m/sec or 1.0 m/sec. on continuous cycles.
